BOBBIN-WINDING murmur.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed September 27, 1906. Serial No; 386,409.

To all whom it may concern:

Be it known that I, JERRY C. LIBERTY, a citizen of the United States ofAmerica, and resident of Easthampton, in the county of HampshireandState of Massachusetts, have invented certain new and usefulImprovements in Bobbin \Vinding Machines, of which the following is afull, clear, and exact description.

This invention relates to improvements in machines for winding orspooling thread and yarn.

.Aniobject of the invention is to provide a machineof simple, inex)ensive and practical construction with capa ilities, in asinglemachine, for the performance of a large amount of work.

Another object of the invention is to provide improved means for varyingthe traverses of the thread guides according to the lengths of quills orspools being wound, and whereby in one'machine some spools comparativelylong and others of less length may be simultaneously ,wound.

Another object is to provide improved means for the holding and carryinof the spools relatively to the mechanism which imparts the windingrotations thereto.

Other objects are to generally improve, simplify, and increase theefiiciency of the machine as will be hereinafter rendered apparent.

The invention consists in the combinations or arrangements of parts andthe constructions of certain of the parts all substantially ashereinafter fully described and set forth in the claims.

In the dra\vings.Figure 1 is a lan view of the windingmachine having auplex organization that is capable of winding two spools at each side ofthe machine b reason of duplicated mechanism therefor. ig. 2 is anelevation at one side of the mach'ne.

Fig. 3 is a sectional elevation as seen be 0nd the plane indicated bythe line 33, Fig. 1,

spool as taken on line 5-5, Fig. 3. Fig. 6 is a sectional view of theparts shown at the left hand portion of Fig. 5, but as drawn on a planeat right angles thereto. Fig. 7-is an end view of one of the spools tobe Wound, showing the end cuts therein to be engaged by thespoolsupporting and rotating means.

Fi 8 is a sectional view on line 8-8, Fig. 3

to illustrate a detail construction to be hereinafter referred to.

Similar characters of reference indicate corresponding parts in all ofthe views.

In the machine shown in the present illustrations, provision is made forthe support and rotation and winding of two axially alined spools orbobbins at one side of the machine, and a like number at the oppositeside.

In the drawings-A represents a frame of a design suitable for support ofthe various fixed and movable parts comprised in the machine; and alongthe middle thereof is a horizontally arranged driving shaft B having adriving pulley C thereon, a worm D at its middle; and comparativelylarge friction wheels E E outwardly therefrom. On suitable extensions aa of the frame at the upper and most widely opposite portions thereofare rocking shafts or bars F- F in axial alinement and adapted to beindividually and independently partially rotated in their su portingbearings, Each of these rock sha ts has at suitably different portionsin the length thereof a frame or bifurcated bracket G and a bracket H,each being affixed on the rocking bar. 'In each yoke shaped bracket G isjournaled for rotation a head stock spindle J having a plain facedroller K atlixed thereon, and adapted, when the yoke is properly swuninward,the rock shaft being correspon ingly rocked,-to frictionally bearperiphera ly on the adjacent friction wheel E.

In the semi-revoluble bracket H is a stemor short shaft L endwiseslidable, but constrained against rotary' movement, andthe particularconstruction and manner of mounting this part I; is clearly representedin Figs. 5 and 6 of the drawings, wherein it is seen that the bracket isformed with a necked down portion b and shoulder 61 and der (1 of theshort shaft is disposed .a spiral spring g. The larger portion of theshort shaft L has a longitudinal groove or spline l L have axiallyextending studs or teats h,

while at the base or portion back from the point of. the teat h at theend of the spindle J are thin opposite radial lugs or fins 2' 2'. Thespools or bobbins w to be mounted in the machine and continuouslyrotated to cause the winding thereon of the suitably guided thread oryarn, have each an axial hole therethrough into which the teats h h ofthe spindles may enter for a short distance; and the spools are made ontheir ends with diametrical grooves a (see Fig. 7), in which theaforementioned lugs or fins i of the rotatable spindle J may engage. Thespoolsare made with transverse grooves 41: on both of the ends thereof,as thereby no care'is required to bring a proper end of the spool injuxtaposition to the inner end of the spindle J.

I The action of mounting the spools between the spindles J and L,preparatory to the winding operation, is by placing one end of the spoolwhile in a slightly oblique position with its end hole in engagementwith the teat of the spindle Land forcing the spool and spindle endwiseoutwardly to let the opposite head of the spool come to a position forengagement by the teat andlugs'of the spindle J; and then byreleasingany pressure in an outward direction on the spool, theconcealed spring 9 in the head of the bracket H will cause a movementofthe spool slightly in the proper endwise directionto perfect theengagement of the spool with the peculiarly formed end of the spindle J.

The construction and arrangement of parts just above described wherebyone spindle L of the pair of spindles J L, is incapable of rotation,conduces materially and in an important way to the value of the machine.It is in this connection to be appreciated that in a machine such as thepresent one, designed for constant or at least long protracted running,-and for the winding of immense numbers of spools or bobbins, theprovisions whereby spindles L are prevented from rotating precludesunnecessary wear and makes comparatively infrequent the requirement forreplacement of the spindles L.

It is, of course, necessary to comparatively frequently. replace thefriction roll carrying. spindles J, but the item of costand troubleavoided by the non requirement of replacing spindles L will in the lifeof one ofthese bobbin winding machines be found considerable. I v

The stop shown as in the form of a thumb from being forced, by itsspring, too far inwardly ordisplaced from its position of sup- I port inthe bracketH when no spool is in supportin engagementbetween the pair ofspindles J and L.

In this machine, capable of simultaguides m are provided .at locationssuitably adjacent or opposite a line between the apli, each thread guideconsisting of an upstanding wire having an eye at its upper endsupported and a clip n which is confined by a binding screw n on eitherof two comparatively long parallel horizontally and longitudinallyranging slide shafts or bars H M ,-the means of support'with capabilityfor sliding movements endswise oppositely of the bars being alforded insuitable bracket like portions of the frame A.

- The thread guides, the clips on which they are mounted, and thesliding shafts on which the clips are supported, are best seen in Fig.4.

Each clip a, is split to form opposite ear lugs 30, through which lugsis passed a clamping screw 1:? by means of which the clips areadjustably held in position on bars M. An arm 31, projects atapproximate right angles to the ear lu 30, and has secured thereto bymeans of a headed screw 34, a wire stran having a vertical arm 32,formed with a threaded eye 35 at its upper end, and having its oppositeend bent into a hook 33, disposed in a plane at right angles to eye 35,hook 3 3 engaging one side face of arm 31, and being engaged by the headof. screw 34.

The means for imparting the slow movements to' the tiread guidesrepeatedly in alternating directions for laying the. thread on therotating spool or bobbins, will be now pointed out.

7N represents a shaft horizontally journaled in, a suitable portion of.the frame A the driving shaft B, and has thereon a worm wheel 0 whichis in-n esh with the aforeshaft. This worm wheel shaft N has on oppositeends thereof heart shaped cams P P, these cams being here shown as setin opposition, although this particular arrangement is not angularlevers Q. of cruciform pivotally mounted near their elbows, asrepresented each of these levers has a slot 8 therein (see F 1g. 2) asuitable portion of the lever carries a stud or roller 25 for hearing onthe edge of the cam, and the more or less nearly neously windingfourspools, four threadhelow and at right angles to the length 0ftmaterial. Sidewise adjacent these cams are at q. The upwardly extendingarm 1* of nut Z; is provided to prevent the spindle L proached ends ofpairs of the spindles J and mentioned worm D on the main or driving Ihorizontal arm of the angular lever is formed as, or rovided with, acomparatively heavy weight u, the effect of which is to keep the lever,by its cam stud, always against and subject to the action of the cam, sothat the expanding portions of the cam will positively produce theendwise movement of the thread carrying bar in one direction and theweight 1.4 will cause the lever to follow the receding portions of thecam and cause the endwise motions of the thread carrier in the oppositedirection, it being noticed that the upwardly extending member of thecam lever has an engagement with the depending bar R rigidly affixed totheslidable thread carrying bar. This depending bar R is verticallyslotted to permit the play of the stud 7) carried by the swinging camlever Q, therein. The stud 'v is made shouldered, as shown in F ig. 8,and with 'a screw threaded portion 12 to receive the binding nut wherebythe stud, through means of the washers '0 v setting against theshoulders at different portions of the length thereof, may be confinedto,and as a part of the upwardly extending arm '1' of the cam lever.'Thestud, therefore, may be adjustably set nearer or farther from thefulcrum of the cam lever whereby will be imparted'longer or shorter backand forth movements of the slide bar for the thread guides so thatthelatter will be made to move back and forth along the spools in long orshprt courses accordingly as the spools being wound in the machine .arelonger or shorter.

The rotary movement of the continuously driven main shaft causesrotation of the wheels E E andof the wheels or rollers K K in frictionalbearing thereon, the latter turning the head spindles between which andthe short shafts L the spools are mounted,

and the spools are thereby rotated to wind the thread guided thereby bythe gradual but constant 1 moving thread guides. And it is apparent thatthe slow back and forth movements of the thread guides are caused by therotation of the worm D which slowly turns the worm wheel andits shaft,and the cams P P thereon, coacting with which are the weighted leversengaging the depending members R of the slidable thread guide carryingbars.

As shown in the drawings, the yokes G with the friction wheels K andhead spindles J together with the brackets H carrying the short shaftsL, are swung outwardly at the right hand end of the machine and ingpositions,

away from peripheral contact with the friction wheel E; while thesecorresponding parts duplicated at the left hand end of the machine areindicated as having their workthe frictionally driven wheel K being inperipheral bearing on the left hand friction wheel, it being perceivedin Fig. 1 that the shaft sections F F on which the last mentioned partsare semi-revolubly mounted, are capable of independent rocking movementsso that each pair of brackets G and H maybe inwardly or outwardly swung,as occaslon may require.

The last referred to spool carrying parts are outwardly swung to thepositions shown at the right hand portions of the drawings at times whenwound spools are to be removed and new spools brought in readiness to bewound.

The friction wheels E E may be faced withrubber orother material for amanifest advantage.

. It will be perceived on reference to Figs. 1 and 2 that upwardly andoutwardly projecting portions or noses Z of the frame serve to limit theoutward swinging or rocking movements of the rocking bars F and so soonas the spools have been properly fully wound. Each of these devices,individual to a single spool winding mechanism consists of a small diskS pivotally mounted at w eceentrically thereof within a bracket 'wtherefor, which has a screw threaded stem 7 which vertically adjustablyengages through a properly located projection or portion of the frame A.Each of the brackets is made with a stop or shoulder a which may engagea laterally projecting stud 7 extended from the side of the disk. Theedge of each disk is preferably knurled or roughened.

At the left hand portion of Fig. 4, the po sition of the eccentricallypivoted disk and its stud 7 relatively to the stop shoulder 2 isrepresented as under normal winding con- .ditions, and while the spoolis yet not fully lifting of the frictionally driven wheel K &

from contact with the friction wheel E the further winding actionat thispoint being terminated without regard to winding conditions in otherportions or the machine. The attendant noticing that a given spool is-motionless will outwardly swing the spool carrying parts, removing thewound spool, replace it by a new spool to be wound, reverse the positionof the eccentric disk S and inwardly return the spool carrying androtating parts for a resumption of the winding operation at thisparticular part of the machine.

As will be perceived from the drawings, Figs. 1 and 2, the spools at oneside of the machine are shorter than those at the other: and as will beperceived from Fig. 3, the studs 0 are carried by the cam lever at oneside at a higher point than at the other for varying lengths oftraverses of the thread guides corresponding to the different lengths ofthe spools; and it will be also noticed in Figs. 1 and 2 that thebrackets H forming one end support for. the spools are endwiseadjustable toward and away from the yoke frames G, as rendered possibleby the provision, as parts of the brackets H, of the collars 8 whichembrace and are adjustably secured by the set screws 9- to therespective rock shaft sections F.

At various places in this machlne are luv bricating devices, severallyindicated by 6 throughout the drawings.

The journal bearing or part through which a shaft or spindle is mountedfor rotation is made with a cavity 5, as represented in detail at theright hand portion of Fig. 5, grease or other lubricant being receivedin this cavity and having communication with the shaft or spindle, isprotected from dust and mud, and also may be forced positively to thebearin by plugs 4 screw engaging in the walls of t e cavity.
